I think the grass can only absorb so much. I think people have said after 4 hrs the grass cannot take anymore up.
Yes I believe so. The whole point of using chelated is that after the leaf has taken up as much as it can, when you water the yard, the chelated iron makes it available through the roots in the soil. If you are only worried about foliar feeding of iron, there is no need for chelated iron.kur1j said:Is this also true for chelated irons as well?
